[REQUIRED] Step 2: Describe the problem
Hello,
I am using Google AdMob for ad mediation in my Flutter application.
I've noticed that when an Interstitial or Rewarded ad is served by Unity Ads mediation, it opens a separate Android activity (or window), which makes it look as if a second app is running on the device.
This behavior is not observed with other mediated networks, such as Liftoff or Mintegral, which display their ads correctly within the current application's context.
Could you please confirm if this behavior (Unity Ads opening a separate activity/window for full-screen ads) is normal and expected for the Unity Ads adapter, or if it indicates a potential integration issue that needs to be resolved?
Thank you for your assistance.
Steps to Reproduce
1- Open the Flutter application on an Android device.
2- Trigger an Interstitial or Rewarded ad request via AdMob.
3- Ensure the ad served is from the Unity Ads network.
4- When the Unity Ads full-screen ad appears, minimize the application (e.g., by pressing the home button or using the multi-tasking gesture).
5- View the recent apps screen (multi-tasking view).
Expected Result: Only the main application should be visible, with the ad being dismissed or running within the app's context.
Actual Result (Issue): The recent apps screen displays two separate application windows—one for the main app and one for the active Unity ad.
